Bossypants

She may be one of the most colorful contributors to TV, movies and even bestselling books (Bossypants), but Tina Fey opted to go monochromatic a black Oscar de la Renta gown and Roger Vivier clutch on Saturday's SAG Awards red carpet.

To say Tina Fey is in no rush to learn the sex of her second baby is an understatement.

The Bossypants author and 30 Rock star, 40, who recently revealed her pregnancy to Oprah Winfrey, says that she and her husband, composer Jeffrey Richmond, 51, have decided to wait to discover their expected child's gender. For 17 years.

Tina Fey appeared on The Oprah Winfrey Show Tuesday to promote her book Bossypants and to participate in a Saturday Night Live reunion. But first she had to get something offer her chest – her baby news!

"You look great," Winfrey asked Fey at the top of the show, "Did I notice … ?"

"It's really happening," the smiling 30 Rock star replied with both hands on her baby bump.

In those restless hours she couldn't sleep, Tina Fey debated in her mind whether she should have a second child, the question soon tormenting her in the daytime, until she couldn't take it anymore.

During a visit to her gynecologist, she broke down.

"I went for my annual checkup and, tired of carrying this anxiety around, burst into tears the moment she said hello," the Emmy winner, 40, writes in her new memoir Bossypants. "I laid it all out for her, and the main thing I took away from our conversation was the kind of simple observation that only an impartial third party can provide: 'Either way, everything will be fine.' "

The 30 Rock star revealed during Wednesday's taping of The Oprah Winfrey Show what her decision ultimately was: She is now five months' pregnant.
